JOHN L. BARKER AND WILLIS D. SLAUSON, OF RAGINE, WISCONSIN.

WAGON-BRAKE LEVER.

SPECIFICATION forming part of Letters Patent No. 253,662, dated February14, 1882.

' Application filed January 3, 1882. (ModeL) To all whom it may concern:

Be it known that we, JNO. L. BARKER and WILLIs D. SLAUSON,0f Racine, inthe county of Racine, and in the State of Wisconsin, have inventedcertain new and useful Improvements in Wagon-Brake Levers and we dohereby declare that the following is a full, clear, and exactdescription thereof, reference being bad to the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecification.

This invention relates to an improved brakeleverclutch for wagons andother vehicles, and it has for its objects to provide a compact devicewhich may be readily attached to a vehicle of any description, which maybe readily and quickly operated, which will hold the brakes withoutdanger of slipping, and in which the clutch mechanism will be securelyinclosed and protected against the weather, as more fully hereinafterspecified. These objects we attain by the devices and mechanismillustrated in the accompanying drawings, in which Figure 1representsa-perspective view of the casing for the clutch mechanism withthe cover removed. Fig. 2 represents atop view of said casing, showingthe clutch in place. Fig. 3

represents a view of the cover detached, showing its inner face. Fig.etrepresents a vertical sectional view of the device; and Fig. 5, a topview of the device complete, with a portion broken away to show thespring employed for holding and returning the parts to a normalposition.

The letter A indicates a circular casing or box, of cast metal having,perforated lugs B, by means of which it may be attached to the wagon orvehicle. The interior of said casing is provided with asegmental flange,O, which is parallelwiththeinnerwallofthecasing,leaving a space, D,between its wall and the said inner wall of the casing. The said casingis also provided with a central boss, E, as indicated.

The letter F indicates a friction-clutch provided with an opening, Gr,somewhat larger than the boss E. The clutch sets loosely in the casing,the opening setting over the boss. The upper end of the clutch, on itsrear face, is provided with a segmental flange, G, which fits in thesegmental space D of the casing.

The lower end of the clutch is provided with a bearing, H, against whichthe lug I on the cover K abuts when the strain is brought upon thebrakes, as more fully hereinafter specified.

The coveris provided with a boss, K, on the inside, which sets inthe'boss in the cover, forminga short journal,which permits the cover toturn freely a properdistance. The cover is also provided with a lug,L,on its inside, which forms a bearing for one end of a coiled spring, M,the other end of which bears against one side of the friction-clutch.

The letterNindicates an aperture in the cover, through which projects 2.lug, N, located on the upper end of the front face of thefrictionclutch, for the purpose hereinafter explained. The front of thecover is provided with a diametrical recess, P, formed by the raisedflanges R, which converge slightly toward their lower ends, and areprovided with bearings S for the lower end of a lever, T, which isfulcrumed to a central bolt, U, which holds the parts together.

The letterW indicates a plate secured over the upper part of the recessP, so as to cover the lower part of the lever and protect it. The leverextends upward below a guard,Y, on the upward extension Z of the cover.The letter A indicates an aperture by means of which thebrake-rod may beattached to the device.

The operation of ourinvention is as follows: The device is fastened tothe wagon or vehicle in any convenient position, and the'brake-rod issecured to the extension Z. When in a normal position the spring keepsthe edge of the clutch in frictional contact with the inner wall of thecasing, locking the cover. When it is desired to turn the cover tooperate the brake the lever T is'brought to bear against the lug N andforce the clutch away from the inner wall of the casing, permitting thebrake to be locked or released, as may be required.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is- 4 1. The combination, with the cylindrical casingadapted to be secured to the wagon or vehicle, of the friction-clutchadapted to work in said casing, the oscillating cover and its lugs, andthe spring for holding the clutch in a normal position, and the leverfulcrulned to the outer face of the cover and adapted to bear against alug on the clutch projecting through an opening in the cover,substantially as and for the purposes specified.

2. In combination with the casing provided with an internal segment andcentral boss, the friction-clutch located in said casing, theoscillating cover provided with lugs and a central boss, the spring forholding the parts normally, and the ley'er for moving the clutch, thewhole arranged to operate substantially in the manner specified.

3. In combination with the casing provided with an internal segment andcentral boss,
